I have a 1989 L98 IROC-Z that weighs 3812lbs with me in it.

So far my best time is 14.4 @ 96mph. That was with all the mods in the sig except at that time I DID NOT HAVE: a fuel pressure gauge (hence, my AFPR wasnt doing anything), headers, SFC, hypertech thermomaster chip, 160 stat, ram air with gutted air boxes and TB coolant bypass.

What should I run now that I have those mods in there? Can I break 13's? Can I trap at 100mph?

I am running a best of 14.46 @ 93

what are your 60 ft times?

 

The Mph seems a little low at lest a 98 mph. my 305 runs 93 mph.

 

That 14.4 @ 96mph is with a 2.1 60' time. I think I can do better than that, but not all that much better.

 

My 60 ft times are 2.0 fairly consistantly.. that's with street tires and stock rear suspension set up.
I would think you should be able to get 1.9's out of yours.
That would bring your ET down around 14.1 or so..
how was the weather when you ran?

 

I'm just comming out of Pont-Rouge Dragway in Quebec. My best time for the day :
14.120
95.95mph
0/60 ft : 2.005
r/t : 0.641

The temperature was approx 28C deg.
